The Lower Class Library was exactly as I pictured it to be. This was actually my first time here, but we were shown the libraries of each Class, albeit briefly, during our Orientation.
The only Library in which we actually got the grand tour of was the general campus library. It was larger than the others, having several sections and floors, a wealth of books and other research materials.
However, the problem with the general Library was that it was only accessible once a student had completed their first three months in Ainzlark Academy. They would be given a special library card that represented their access to the library. Of course, this card was bound by the Class Points a student had accumulated during the time of Library registration.
That was why three months were given to new entrants, so they could earn as many class points before registration.
